Any sling maker is good. It's a simple thing really, so all you really need to look for is someone that has the colors you want. I went with a Sling Braid, which is an AT retailer. I ordered my first, and I didn't really like the way it matched my bow, and Ben made me a new sling, free of charge! That's awesome customer service!
I got a really good one to match my Strother in predator camo colors. Just go to e-bay and search "strother archery" and a custom wrist sling will come up in the results. Contact the maker and he can do any custom color combo you want. Para cord and leather and quality made. I think I paid about $12.
To follow up - I ordered a sling from SlingBraid and had it just a few short days later. Great service and a great product for a very reasonable price. Thanks for the advice gents!
t's actually from a Tru Glo sling. It's what comes with them. I buy them just for the metal piece and then take the leather that comes with my slingbraid and donate it to another archery, usually a kid at the range that doesn't have one.
Very cool! I'm liking the metal mount piece. A lot better than the leather bits... http://www.basspro.com/TruGlo-Centra-Bow-Sling/product/54239/-976030
